-=head1 NAME
-
-Catalyst::Plugin::Static::Simple - Make serving static pages painless.
-
-=head1 SYNOPSIS
-
- use Catalyst;
- MyApp->setup( qw/Static::Simple/ );
-
-=head1 DESCRIPTION
-
-The Static::Simple plugin is designed to make serving static content in your
-application during development quick and easy, without requiring a single
-line of code from you.
-
-It will detect static files used in your application by looking for file
-extensions in the URI. By default, you can simply load this plugin and it
-will immediately begin serving your static files with the correct MIME type.
-The light-weight MIME::Types module is used to map file extensions to
-IANA-registered MIME types.
-
-Note that actions mapped to paths using periods (.) will still operate
-properly.
-
-You may further tweak the operation by adding configuration options, described
-below.
-
-=head1 ADVANCED CONFIGURATION
-
-Configuration is completely optional and is specified within MyApp->config->{static}.
-If you use any of these options, the module will probably feel less "simple" to you!
-
-=over 4
-
-=item Forcing directories into static mode
-
-Define a list of top-level directories beneath your 'root' directory that
-should always be served in static mode. Regular expressions may be
-specified using qr//.
-
- MyApp->config->{static}->{dirs} = [
- 'static',
- qr/^(images|css)/,
- ];
-
-=item Including additional directories (experimental!)
-
-You may specify a list of directories in which to search for your static files. The
-directories will be searched in order and will return the first file found. Note that
-your root directory is B<not> automatically added to the search path when
-you specify an include_path. You should use MyApp->config->{root} to add it.
-
- MyApp->config->{static}->{include_path} = [
- '/path/to/overlay',
- \&incpath_generator,
- MyApp->config->{root}
- ];
-
-With the above setting, a request for the file /images/logo.jpg will search for the
-following files, returning the first one found:
-
- /path/to/overlay/images/logo.jpg
- /dynamic/path/images/logo.jpg
- /your/app/home/root/images/logo.jpg
-
-The include path can contain a subroutine reference to dynamically return a list of
-available directories. This method will receive the $c object as a parameter and
-should return a reference to a list of directories. Errors can be reported using
-die(). This method will be called every time a file is requested that appears to
-be a static file (i.e. it has an extension).
-
-For example:
-
- sub incpath_generator {
- my $c = shift;
-
- if ( $c->session->{customer_dir} ) {
- return [ $c->session->{customer_dir} ];
- } else {
- die "No customer dir defined.";
- }
- }
-
-=item Custom MIME types
-
-To override or add to the default MIME types set by the MIME::Types module,
-you may enter your own extension to MIME type mapping.
-
- MyApp->config->{static}->{mime_types} = {
- jpg => 'image/jpg',
- png => 'image/png',
- };
-
-=item Apache integration and performance
-
-Optionally, when running under mod_perl, Static::Simple can return DECLINED
-on static files to allow Apache to serve the file. A check is first done to
-make sure that Apache's DocumentRoot matches your Catalyst root, and that you
-are not using any custom MIME types or multiple roots. To enable the Apache
-support, you can set the following option.
-
- MyApp->config->{static}->{use_apache} = 1;
-
-By default this option is disabled because after several benchmarks it
-appears that just serving the file from Catalyst is the better option. On a 3K
-file, Catalyst appears to be around 25% faster, and is 42% faster on a 10K file.
-My benchmarking was done using the following 'siege' command, so other
-benchmarks would be welcome!
-
- siege -u http://server/static/css/10K.css -b -t 1M -c 1
-
-For best static performance, you should still serve your static files directly
-from Apache by defining a Location block similar to the following:
-
- <Location /static>
- SetHandler default-handler
- </Location>
-
-=item Debugging information
-
-Enable additional debugging information printed in the Catalyst log. This
-is automatically enabled when running Catalyst in -Debug mode.
-
- MyApp->config->{static}->{debug} = 1;

+=item Bypassing other plugins
+
+This plugin checks for a static file in the prepare_action stage. If the
+request is for a static file, it will bypass all remaining prepare_action
+steps. This means that by placing Static::Simple before all other plugins,
+they will not execute when a static file is found. This can be helpful by
+skipping session cookie checks for example. Or, if you want some plugins
+to run even on static files, list them before Static::Simple.
+
+Currently, work done by plugins in any other prepare method will execute
+normally.
+
+=item Debugging information
+
+Enable additional debugging information printed in the Catalyst log. This
+is automatically enabled when running Catalyst in -Debug mode.
